T0 all wiz-0m t my concern:

Be it known that I, LEONARD R. OAKLEY. a subject of His Majesty the King of Great Britain, Aand a resident of Watertown, in

the county of Litchfield and State of Con-` necticut, have made and invented certain new and useful Improvements in Buttons, of which the following is a specification.v

My invention relates to metallic buttons l0 and particularly to thatrv type wherein the head and cap are made separately and joined together. This button -is ordinarily used where it is desired to have an ornamental cap which is suitably embossed or composed of a metal different from that of which the body portion of the button is formed.

lHeretofore it has been customary to flange both the body portion of the button and the cap and to then subject the same to the action of suitable swedging or forming dies whereby the flanges were compressed, the flange of the cap being compressed inwardly toward its lower free extremity so as to thereby ,interlock with the flange of the body. I have found, however, that while this securement prevents the separation of the cap from the bodyfit does not always prevent the turning of the cap with relation to the body, and which turning will in time allow the sepa-ration of the two and also in theinterim gives the impression of insecurity to the button. It is accordingly the object of my invention'to provide an improved type of fastening between the cap and the body portion of the button so as to positively prevent the cap from loosening or from turning with relation to the body portion of the button.

With the foregoing and other objects in view, my invention consists in the improved button illustrated in the accompanying drawings and hereinafter describedv and claimed, and in such variations and modifications thereof as will be obvious to those skilled in the art to which my invention relates, it being understood that changes may be made within the scope of what is claimed without departing from the spirit thereof.

The preferred embodiment-of my invention is disclosed in the accompanying dra-wingslwherein 1 Figure 1 is a view in side elevation of the body portion of my improyed button ernbodying the characteristicI features of my invention;

Figure 2 is a bottom plan view thereof;

Figure 3 is a view in vertical vsection of the cap; l

Figure 4 is a view in vertical section of the button having the ,ca securely attached to the body portion; and

Fi re 5 is an enlarged sectional view showing" the connection and juncture between the capand the upturned flange of the body portion of the button.

Referring specifically to the several views, wherein similar reference numerals designate corresponding parts throughout, the body portion 10 of the button is provided with the usual hub 11, outwardly from which projects the top 12 which terminates in the upwardly and j outwardly flared flange 13. This flange is provided with the indentations or corrugations 14, preferably stamped therein, as clearly illustrated in Figure 1. These indentations or corrugations stop short of the upper extremityof the flange, as illustrated.. The cap 15, as illustrated in Figure 3, is of the customary formation and includes the downwardly extending flange 16. This cap is ornamented in any suitable or desired manner and in some instances is composed of a metal which will lend a pleasing and bright appearance to the button.

In the securementof the cap 15 upon the topof the button, it is placed directly upon the flange 13 andy the two are then subjected to the action of a suitable press (not shown), whereby the flange 16 of the cap is forced inwardly to form the inwardly flared flange 17 of Figure 4. The'pressure of the dies of the press is sufficient to cause the metal of the flange 17 to flow into the corrugations 14 of the flange 13 and in so doing form the inwardly extending teeth 18, which engage the side walls of the corrugations 14 and thus hold the cap against turning. The cap being thus securely held against'turning, and the outward tapering of the flange 17 holding it against displacement,A thus rigidly .locks and binds the two together.

Having 'thus described and explained my invention, I claim and desire to secure by Letters Patent:

1.,*The method of securing a button cap to the body of a button consisting in pro# viding the upper and outwardly flared flange of the body of the Abutton with *y peripheral parallel indentations or corruations, "assembling a cap-u n the flared ange, with the downwar ly extendingflange of the cap encompassing the flange of the body of the button, and subjecting the -two flanges to external pressure and -causing the metal of the flange of theeap to flow into the parallel indentations or corrugations of the flange of the body of the button and securely lock the two in place.

2. A button of the character described comprising a body portion provided with an upwardly extending flange'inthe form of an annulus having indentations or corru-fv gations formed therein, the annulus remaining unbroken and a cap. assembled upon the said flange and with the metal of the cap extending into the y,said indentations or corrugations to thereby form teeth 4engaging the side walls of said indentations and corrugations and holding the cap against movement with relation to said button body.

3, A button comprising a body portion having an 'upwardly extending flange, said flange provided with a plurality of parallel indentations formed about the same and
